Claims.

This invention relates to hair curlers. One object of the presentinvention is to pro vide a hair curler which comprises a rod or mandrelon which the hair is wound and held temporarily preliminary to thetransfer of the coil of hair to a holding device such as for example abobby pin, said hair curler also having a clamping member swingablymounted on said mandrel, the construction and arrangement of the mandreland clamping member being such as to simplify the manufacture andassembly of said mandrel and clamping member.

Another object of this invention is to provide a hair curler which isconstructed to receive a hair holding device, for example, a bobby pinor thelike, in such position in relation to the curler as to allow thecurler to be rotated while the holding device is held stationary duringall or a part of the rotation of the curler for winding the hairthereon.

Another object of the invention is the provision of a hair curler of thetype described which is constructed and arranged to facilitate thewinding of the hair on the mandrel and the transfer of the coil of hairfrom the .curler to the holding device as well as to facilitate thedisengagement of the curler from the coil of hair in transferring thelatter to the holding device.

A further object of the invention is to construct and arrange themandrel and clamping member in such manner that the curler is formed ofa small number of parts which are easily assembled in operativerelation.

A further object of the invention is to provide a hair curler having amandrel and a swingably mounted clamping member held in operativerelation to the mandrel by spring means which also biases the clampingmember into clamping relation with the mandrel.

A yet further object of the invention is generally to provide a haircurler of improved construction and operation.

The above and other objects, features and advantages of the inventionwill be fully understood from the following description considered inconnection with the accompanying illustrative drawings.

In the drawings:

Figure 2 is a side view, in elevation, of the hair curler taken at rightangles to the view of Figure 1; Q

Figures 3 and 4 are sectional views on the lines 3-3 and 4--4,respectively, of Figure 1;

Figures 5 and 6 areside view of the curler illustrating the manner ofusing the same;

Fi ure 7 is a view similar to F ure l showin anothervform of theinvention;

Figure 8 is a perspective view of the clamping member of the curlerillustrated in Figure 7; and

Figures 9 and 1.0 are views similar to Figures 1 and 2, respectively,showing et another form of the invention.

Referring now tothe drawings in detail, the hair curler l0 embodying thepresent invention comprises a mandrel or cylindrical rod formed as hereshown of the interfltting parts 12 and M. said mandrel is preferablymade of a plastic but can be made of any other suitable material. sheetmetal or other suitable material is mounted on said mandrel in swingablerelation thereto for movement into. and out of clamping relation withthe hair which is wound thereon preliminary to the transfer. of the coilof hair to a holding .device, such as for example, a U-shaped springmember l8 here shown as a bobby pin as illustrated in Figures 1 and 6.

Referring now more particularly to the construction of the mandrelformed of the parts 12 and 114, themandrel part .12 is provided with alongitudinally extending opening or bore 20 and the mandrel part it isprovided with a reduced endportion 22 which fits snugly into said bore2.0. The mandrel part l2 is also provided with a side opening or slot 24which leads into the bore 20 from one side of the mandrel. The otherpart ll of the mandrel is provided with a longitudinally.extendingrecess or opening 28 which is open at .one end of the mandrelto receive the leg 28 of the hair holding device I8.

The clamping member 16 comprises a longitudinally extending part30.which is .curved transversely, as illustrated in Figure 4 andconforms to the curvature of the mandrel. Said clamping member isprovided near one end thereof with a laterally projecting part or tongue32 which, as here shown, is formed by striking the same from a part ofsaid clamping member. Said tongue 32 extends into the bore 20 of mandrelpart l2 through the slot 24. Spring means hereshown as a compressionspring 36 is positioned in bore 20 of mandrel part l2 and bears at oneend thereof against tongue .32 of the clamping member and at theopposite end thereof against the end surface 38 of reduced "portion 22of mandrel part l4. Tongue 32 is provided with a portion 40 A clampingmember .16 formed of which projects into spring 36 axially thereof formore securely holding the clamping member in connected relation to themandrel, said portion 40 preventing movement of the tongue out throughslot 24. The mandrel part I 2 is provided with a recess 42 to receivethe end portion of the clamping member when the latter is pivotallymoved or swung outof clampingrelation to the mandrel as illustrated inFigure 5. It will be noted that the end portion 44 of the clampingmember, from which the laterally projecting part or tongue 32 is struckout, forms a finger piece to facilitate manipulation of the clampingmember in moving the same into and out of clamping relation with themandrel.

It will be noted that the clamping member I6 is held in position on themandrel for pivotal or swingable movement with respect thereto by thespring 36 and that in the pivotal movement of the clamping member thetongue 32 thereof engages the edge 46-0f the mandrel part I2, at theslot 24, as a fulcrum for said clamping member. Spring 36 not onlyserves to hold the clamping member I6 in swingable or pivotal relationto the mandrel but also biases the clamping member into clampingrelation with the mandrel and resiliently holds the latter in saidrelation as well as resiliently opposing movement of the clamping memberto its retracted position out of clamping relation with the mandrel.Thus spring 36 is operatively connected to the clamping member forsecuring the latter in operative relation to the mandrel.

Upon the insertion of end portion 22 of mandrel part I 4 into bore 20,spring 36 is partially compressed and thereby holds the clamping memberI6 in clamping relation to the mandrel and permits, upon furthercompression thereof, the movement of the clamping member to itsretracted position out of clamping relation with the mandrel. Mandrelpart I4 may be maintained in removable relation to mandrel part I2 whilesecured to the latter against unintended removal by the snug fit ofreduced end portion 22 in bore 20. "However, it is within the scope ofthe pres.- ent invention to provide additional means for securing themandrel parts to each other, for example, by screw threading the endportion 22 of mandrel part l4 and the adjacent surface of bore ofmandrel part I2 or by inserting a pin transversely through mandrel partI2 and portion 22 of mandrel part I4, to prevent rela tive longitudinalmovement between said parts, or by adhesively securing said portion 22to the adjacent surface of part I4.

In the form of the invention illustrated inFigures 7 and 8, the haircurler IIIA comprises a mandrel having a tubular member or part 50 whichextends for the full length of the mandrel and which provides the latterwith a longitudinally extending opening or bore 52 for the spring 54. Acylindrical rod 56 is fixed within said tubular member 50, being securedtherein in any suitable way, such as for example, being tightly fittedin the tubular member or adhesively secured therein. Members '50 and 56are preferably formed of a plastic, for example, cellulose acetate, andif desired rod 56 may be secured in member 50 by fusing the adjacentsurface of said members to each other by heat or by a solvent for thecellulose acetate. Rod 56 is provided with a longitudinally extendingrecess 58 which is open at one end of the mandrel to receive the leg 28of the bobby pin I8 in the same way as illustrated in Figure 1 withreference the hair curler I0.

The clamping member 60, which is preferably formed of sheet metal, has alongitudinal transversely curved part 6 I, conforming to the curvatureof the mandrel and is provided at one end thereof with a lateral part 62which projects into the opening 52 of the mandrel through the sideopening 64 which corresponds to the opening 24 of the hair curler I0.The spring 54 bears at one end thereof against said lateral part 62 ofthe clamping member and at the opposite end thereof against the adjacentend 66 of rod 56 and resiliently holds the clamping member in clampingrelation to the mandrel. An operating member 68 is slidably fittedwithin tubular member 50 and is movable longitudinally thereof formovingthe clamping member 60 to a retracted position out of clamping relationwith the mandrel as illustrated in dotted lines in Figure I. Saidoperating member 68 is provided with a cylindrical portion 10, whichfits within the tubular member, a reduced integral portion "I 2 forminga peripheral shoulder 14,

, and an integral end projection 16, which extends into an opening I8provided in the lateral part 62 of the clamping member. Said operatingmember is also provided with an integral reduced end portion 60 whichprojects outwardly of the tubular member and forms a push button for theoperating member. A collar 02 is secured to the adjacent end of thetubular member 50 in position to engage the peripheral shoulder 84 ofthe operating member 68 for limiting the movement .of the latter to itsretracted position. It will be understood that, the clamping member 60is movable to its retracted position against the action of spring 54 bypressing on push button 80 of the operating member 68 and that whenpressure on said button is released, the spring 54 moves the clampingmember into clamping re- .lation with the mandrel.

having a longitudinally extending recess 92 open at one end of themandrel to receive the leg 28 of the bobby pin I8. The other end of thetubular member 86 is closed by a cylindrical part 94 which has anintegral projection96 adhesively or otherwise fixed to the inner surfaceof the tubular member. The clamping member 88 comprises the mainlongitudinally extending part 98, which is curved transversely toconform to the curvature of the mandrel, a lateral part I00 whichprojects into the longitudinally extending opening 'or bore I02 oftubular member 86 through the side opening I04, and a laterally offsetlongitudinally extending part I06 which has a reversely bent laterallyextending portion I06 which projects through an opening IIO formed inthe tubular member 86. A spring H2 is positioned within the opening I 02of tubular member 86 and bears at one end thereof against the innersurface of part I08 of the clamping member, the other end of said springbeing received in a recess II4 formed in the inner side of the tubularmember 86, opposite to the opening IIO through which said part I08 ofthe clamping member projects. It will be understoodthat said spring 2resiliently moves the clamping member 88 into clamping relation with themandrel and-resiliently opposes movement of said clamp-- ing member to aretracted position out 'of I said clamping relation, and that saidclamping mem-- her is movable to its retracted position by'pressureapplied to the part I08 of the clamping member against the action ofspring I 12; In assembling the parts of the hair curler 'l0B,'theclamping member 88 is placed in position before the part 94 is attachedto the tubular member- 86. 'More particularly, said clamping member isinserted through the open end of the tubular member which is thereafterclosed by said partv this invention to form said tubular member in twopieces secured to each other along their adjacent longitudinallyextending edges, in which case, the clamping member 88 can :be mountedin position on one of said pieces before it is se-- cured to the otherpieces.

It will be understood that in theuse of the hair curler Ill, forexample, the end portion E of a strand of hair H is positioned..betweenthe retracted clamp l6 and themandrel of the hair curler, asillustrated in Figure 5. Then the clamp is allowed to move into clampingrelation withthe mandrel to hold the hair on the mandrel, and:

then the mandrel is rotated to wind the hair thereon and around theclamping member as illustrated in Figure 6. It will be understoodfurther that the bobby pin or other holding device it is mounted on themandrel as illustrated in Figures 1 and 6 before the hair is wound onthe mandrel, so that upon the completion of the winding operation thebobby pin is in position to receive the coil of hair between theopposite legs of the bobby pin, when said coil of hair is movedlongitudinally of the mandrel for transferring the coil of hair to the.bobby pin and for disengaging the hair curler from said coil of hairand from the bobby pin which thereafter holds the coil of hair.

Further it will be understood that the recess 26 in the mandrel permitsrelative turning movement between the bobby pin and the mandrel when thelatter is rotated for winding the hair thereon, so that the bobby pincan be held against turning movement during all or any part of therotation of the mandrel whereby to wind the strand of hair close to thehead without engagement of the side or leg 28 of the hobby pin with thehead, thus permitting the strand of hair to be wound into a coil forsubstantially the full length thereof from the head to the free end ofsaid strand. It will be understood that the hair curlers A and WE areused in the same way as just described with reference to hair curler 10.

While I have shown and described the preferred embodiment of myinvention, it will be understood that the latter may be embodiedotherwise than as herein illustrated or described and that in each ofthe forms of the invention herein disclosed certain changes in thedetails of construction and in the arrangement of parts may be madewithout departing from the underlying idea of the invention.Accordingly, I do not wish to be limited to the constructions hereinspecifi- Preferably. the tubular member 86 is formed in one piece and isperiph-. erally continuous, but it is within the scope of eallyillustrated or described or -to any' of them the scope of theappendedclaims.
